Ok looking at making the car a little more enviormentally freindly...(AKA local ministry has created a crew of 'smog cops', a mobile unit that likes to take a look see for emissions violations. Anyhow, I found the MAC catted H pipe to fit my MAC long tubes..however the piece has the air line to the smog pump. Now since my heads do not have the emissions port to run the line from the heads to the smog pump line, I can't really run a line from the smog pump to the cats from what I can tell. Now if I don't run the air line from the smog pump to the cats, will the cats be damaged as a result of not running the above mentioned line? Can I crimp off the line at the H like my present pipe has? Or will the lack of a line pumping air to the cats damage them?
